Application filed April 26, 1927. Serial No. 186,649.

My invention relates to a stop or sentinel to be used in connectionwith a window case ing to. limit the swinging movement ofthe w ndow sash therein.

In the construction of windows in which the sash is pivoted to swing inwardly at its upper end, itis frequently desirable to limit the swinging of thesash at a certain point so as to allow a vent; at the upper end there of. Also in swinging a sash inwardly in this manner there is dangerthat the sashmay drop from its upper closed position when it is desired to move it into a *re'versedposition.

It is an object of myinvention to provide.

a guard or sentinel to he used in connection with the casing so as to furnish a stop for the sash and prevent its swinging inwardly beyond acertain point. It is desired to form such a stop which will. be easily releasable swing past the same into openpositionfl It is also an object to provide a stop of and mounting andautomatic in 'itsoperation.

Referring to the drawingherewith, Fig. 1.

is a perspective detail of a section of winon; c Fig. 2 is a broken section of theupper end of the window casing showing my invention employed in connection with a swinging sash mounted in said casing. Fig. 3is top plan view of the invention, the casing being shownin horizontalsectioirthe sash being shown in open position engaging the sentinel as the sash is closed. F 1g. 4 is a view simllar to that shownin Fig. 3 with the window sash moved upwardly and the sentinel in closed position; and Fig. 5-is a'sideelev'ation of the sentinel removed'from thecasing.

My invention may be employed with any ordinary type of'window in which the sash 'is mounted to swing on a pivot at its lower and forming a facing forthe window frame withinthe jambf The window has the usual side plates or jamhs 4 between which the sash is adapted to move. I I have shown somewhat 'diagrarmnatically. a sash 5 which is pivoted on pins 6 at its. lower end, fitting within any desired'support, such asthe window jamh 4:. When the said sash is erect in closed position, it is adapted tocontact with the outerface plate 2 which limits its movement in an outward direction. It is contemplated that the sash may he swung on its pivots 6 inwardly sons to reverse the position of the sash and expose the outer face thereof for cleaning and also to at the upper end" struction ofthis plate may be seen particularly from Fig. 5; Ithasan arm 8: at one end which has an OPGIlHlg 9 therein to receive a pivot member 10 which, under ordinary circumstances, may be a nail orsimilar de-- vice in ordinary use. The forward end of the guard is pointed at 11 and provides at one side thereof a cam face 12 adapted to contact with'the window sash. Beyond this cam face adjacent the arm 8 is a shoulder 13 which acts as a contact member tent-against the faceplate 3 of the window casing, as shown in Fig. 3. i

The sentinel is mounted within a slotl l in the forward side of the window jamh. This slot-is of sutficient width to receive the sentinel plate and is inclined upwardly, as shown particularly in Figs. 1 and 2. The slot or recess 14 is such as would be made Bil by the'cut of'a saw in the corner-of ar vwindow jamh and is of such shape as to receive the triangular-forward end of the sentinel. l/Vhen the sentinel plate is fitted within this recesswith the outer cam face-12 flush with p the edge ofthe window jamh, as shown in Fig. 4, a nail 10 may be driven at an angle transversely through the slot. so as to pass through the opening 9 and form a pivot for the plate, After this has been done, the forward face plate 3 of the casingis set in posit-ion so that the shoulder 13 will fit against the same when the sentinel is in open position to extend into the path of the swinging sash.

In the use of this device, the force of gravity will normally hold the sentinel plate into the position shown in F ig. 1 extending directly out into the path of the sash so that when the sash swings inwardly it will contact with the sentinel and will be stopped at that point. When it is desired to release the sash from the sentinel, the operator will push upwardly on the sash and throw the sentinel plate into the recess 14 with his thumb and hold the sentinel in that position until the sash has been moved partly past the sentinel. The sash may be then swung into any desired position free of the sentinel. lVhen the sash is again thrown into closed position, the edge of the sash will contact with the cam face 12 of the sentinel and automatically move it back into its closed position, shown in Fig. 4, and it will not therefore interfere with the closing of the sash. It will be noted that the construction of the sentinel is exceedingly simple and that it may be installed with a minimum of labor and expense. It will only be necessary to cut the recess 14 with a saw blade of the proper width and to then secure the sentinel in position with an ordinary nail. The catch is exceedingly simple in its construction and reliable and accurate in its operation.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

1. In a window including a casing and a sash therein pivoted at its lower endto swing inwardly, the combination of a triangular-shaped plate having an arm at one end with a pin receiving opening therein, said plate being adapted to fit within an inclined slot in said casing and to fall by gravity into open position in the path of said sash and a pivot pin extending through said opening.

2. In a window including a casing and a sash therein pivoted at its lower end to swing inwardly, the combination of a triangular-shaped plate having an arm at one end with a pin receiving opening therein, said plate being adapted to fit within an inclined slot in said casing and to fall by gravity into open position in the path of said sash and a pivot pin extending through said opening.

8. In a window including a casing and 9.

sash therein pivoted at its lower end to swing inwardly, the combination of a triangulanshaped plate pivotally secured within a slot in said casing, said slot being inclined upwardly so that said plate will swing by gravity into open position in the path of said sash, and means to limit the swinging of said plate.

4. In a window including a casing, and a sash pivoted therein to swing inwardly at its upper end, the combination of a stop plate pivoted at one end in an inclined position in said casing and adapted to swing by gravity into the path of said sash, said plate having a shoulder thereon adapted to engage said casing to limit the movement of said plate and retain said plate in sash supporting position.

In a window including a casing, and a sash pivoted therein to swing inwardly at its upper end, the combination of a stop plate pivoted at one end in an inclined position in said casing and adapted to swing by gravity into the path of said sash, said plate having a shoulder thereon adapted to engage said casing to limit the movement of said plate and retain said plate in sash supporting position, the forward side of said plate having a cam face to be engaged by said sash when it is swung upwardly, for the purpose described.

6. In a window, a casing, a sash therein pivoted to swing inwardly within said casing, and a stop plate pivoted within an up wardly inclined slot in said casing and held by gravity in an open position extending outwardly from said slot and supported by said casing in open position.

7. In a window, a casing, a sash therein pivoted to swing inwardly within said casing, and a stop plate pivoted within an upwardly inclined slot in said casing and held by gravity in an open-position extending outwardly from said slot and supported by said casing in open position, said plate being free to be moved into closed position by said sash when it is swung upwardly past said plate.

In testimony whereof I hereunto ailix my signature this 23rd day of April, A. D. 19:27.
